Today I successfully read the ROM off Pearl's ECU. The file has been uploaded to github so people can assist with hacking it so we can tune our VK56VD engines to their full ability.
This is a dedicated thread for this so that anyone interested can assist. To start with I would apreciate anyone who is using a scan gauge or equivalent could post up the hexademical addresses for each of the items in your gauges.
All help is greatly appreciated and credit will be given in the hack or README.
Michael, this is wayyy over my head but am very interested in what you’re doing.
If you could manipulate the ECU so that the infotainment system restarts straight up on last setting rather than running through the startup warnings each and every time may very well save people’s sanity. 😃
These things get hacked / cracked because people want to change things. It is a learning exercise.Quote:

Are things are checksummed? Encoded in some way? etc, etc. Can you re-load the original binary if you make an error?
You might just turn an expensive ECU into a paperweight.
No and I don't need to. The only reason I would need to know what the processor is is if I was going to write new code. What I am wanting to do is modify output based on input not create a new OS or extend/add to/modify the native OS.Quote:

Never, ever, EVER, E_V_E_R, make more than 1 change at a time when tuning it's a sure fire way to create a diagnostic nightmare. Always save each change as a new file so you can go back and see what change had what effect.Quote:
